Description
Technical field
The present invention relates to be used for make the anti-false fiber of the paper of banknote, marketable securities, more specifically refer to a kind of composite anti-counterfeiting fiber, it is false proof that this composite anti-counterfeiting fiber not only has a line, but also have that the two wires is false proof, the electromagnetic property of three-way false proof usefulness and optical characteristics.
Background technology
Amorphous alloy has just begun progressively to grow up since nineteen sixty, U.S. professor Duwez invented rapid quenching technique, because the institutional framework of non-crystaline amorphous metal uniqueness, preparation technology, excellent material property efficiently make it become a theme of material science worker special concern.In in the past 40 years, be accompanied by the continuous progress of amorphous material basic research, preparation technology and application product exploitation, all kinds of amorphous materials have progressively moved towards practicability.From the magnetic characteristic angle, amorphous fiber can be divided into three major types, be Fe (iron) base of direct magnetostriction, Co (cobalt) base and the zero basic non-alloy fiber of magnetostrictive Fe-Co (iron-cobalt) of negative magnetostriction, they show big Barkhausen (Barkhausen), Ma Texi (Matteucci) and giant magnetoresistance effect respectively.Utilize these effects also can make amorphous fiber be used for pulse generation element, miniature transformer, surface mount inductance, anti-theft tag, rotary encoder, current sensor, displacement transducer, data handwriting pad etc.
In the document, about non-crystal metal fibre magnetic card and decision maker thereof, number of patent application is the decision maker that 01115974.X has reported a kind of non-crystal metal fibre magnetic card of card International Technology company development at home.This device is by detecting the magnetic signal that this noncrystalline magnetic metal fiber is passed through, and judged the good and bad feature of the magnetic card that inserts by detecting signal.
What in addition, U.S. Pat 4835028 (19890530) had been reported the modification paper product that is added with particular dye of can antistatic duplicating and accompanied the amorphous magnetic striction wire in the middle of two layers of paper is used to monitor the paper products (can be considered a kind of anti-theft tag) of this kind paper by article surveillance zones.U.S. Pat 6556139 has been reported a kind of magnetic labels that is attached on the commodity, has glass to coat amorphous magnetic microfibre in this label, utilize its externally the response under the magnetic field come recognition value.Yet, do not see as yet that up to the present relevant amorphous fiber is used for the report of marketable securities paper false proofs such as banknote.
At present, known cheque paper generally adopts technology such as watermark, safety line, false proof disk and anti-false fiber.With regard to anti-false fiber, general colored string, animal fiber, chemical fibre, the coloured or colourless fluorescent fiber of adopting, the public reaches false proof purpose by the existence of fiber in the identification paper, and the characteristic that fiber itself does not generally have machine readable to detect, therefore it can only be used for a line false proof (naked eyes are visual), just can't realize the purpose of two wires false proof (specific electromagnetic property can be machine-readable) and three-way false proof (" expert " analyzes).
Along with the progress of science and technology and the continuous development of anti-counterfeiting technology, people more and more hanker after a plurality of popular anti-counterfeiting characteristics and machine readable anti-counterfeiting characteristic and the anti-counterfeiting characteristic can " expert " analyzed are combined, and realize multiple anti-fake.Traditional anti-false fiber can not adapt to above demand as safety line.
Summary of the invention

In preparation, preparation technology is according to the difference of outer carrier material and difference.The carrier that the amorphous alloy fiber skin is coated can be organic high molecular compound or polymer, also can be silicate material.
When the outer carrier that coats of amorphous alloy fiber is organic high molecular compound or polymer, the material (as rare earth luminescent material) that will have an optical characteristics is milled and is sieved, join in the organic high molecular compound or polymer under the molten condition (as thermoplastic polymer) in required ratio, and add auxiliary agents such as plasticizer, viscosity modifier and antioxidant in right amount, fully mix, then this mixture is coated with or sticks to the amorphous alloy fiber skin and get final product.
When the outer carrier that coats of amorphous alloy fiber is silicate (as glass), with glass as carrier, optical characteristics material (as the rare earth material) powder of a certain proportion of special chemical composition of mixing, they are all sieved, evenly mix through fine grinding, burn till optical characteristics glass under certain condition, and be blow molded into glass tube, and cool off.
Then the non-crystaline amorphous metal rod is placed in the glass tube, make alloy melting in the glass tube lower end with induction coil, make glass tube softening simultaneously, pull out a capillary glass tube with a tensile machine from the glass tube bottom, metal bath embeds wherein, in drop-down capillary process, sprays cooling fluid continuously to capillary with nozzle, make alloy rapid solidification wherein, form the anti-false fiber that glass coats.
Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
